There is a longish review that has the contents here:

https://chesscafe.com/book-reviews/the-triangle-setup/

Even though the contents and the review seem to suggest that only Nc3+e3 is discussed, Nf3+e3 is also covered. Sorry I did not get a chance to check  my DVD yesterday, I will do so tonight.

I got it for fun. It seems to me that Krasenkow did a very good job explaining what the opening's all about, without overselling it but keeping the discussion interesting. If memory serves, he has 8 different videos on the main line Noteboom. But he also covers the early deviations quite well (he starts the DVD at 1 d4 d5 2 c4 e6 3 Nf3/Nc3), for example having 3 or 4 segments on the Stonewall and the Catalan stuff (where we take on c4 and keep the pawn). The only thing that seemed strange to me is how he only has a single video on the Marshall Gambit (he calls it "the Slav Gambit" which is something else), he takes the pawn and even takes g2 if white blocks the check with Be2, he says "white definitely has compensation for one pawn so let's take two." He did show a lot of lines but not a lot of guidance. There are also some pgn's though that can come in handy.
